There seem to be a large number of changes to trunk that have not been merged into branches/release. Perhaps a lot of merges were forgotten after the bug fixing sprint. All of the libraries listed below are suspect, although some may just be holding changes until after the release. "svn diff" can be used to see exactly what changes have not been merged. Here is a simple Windows batch file that eases typing; perhaps someone could post a Unix equivalent. @echo off if not %1$==$ goto usage_ok echo Usage: unmerged library-name goto done :usage_ok svn diff %2 %3 %4 %5 %6 http://svn.boost.org/svn/boost/branches/release/boost/%1.hpp http://svn.boost.org/svn/boost/trunk/boost/%1.hpp svn diff %2 %3 %4 %5 %6 http://svn.boost.org/svn/boost/branches/release/boost/%1 http://svn.boost.org/svn/boost/trunk/boost/%1 svn diff %2 %3 %4 %5 %6 http://svn.boost.org/svn/boost/branches/release/libs/%1 http://svn.boost.org/svn/boost/trunk/libs/%1 :done If your library has changes that need to be merged, please do so right away. I'll hold off on the beta until Monday morning to give folks a chance to do merges and let tests cycle. --Beman accumulators algorithm any array asio assign bimap bind circular_buffer compatibility concept concept_check config conversion crc date_time detail disjoint_sets dynamic_bitset exception flyweight foreach format function function_types functional fusion gil graph integer io iostreams iterator lambda math mpi mpl multi_array multi_index numeric optional parameter pool preprocessor program_options property_map proto ptr_container python random range rational regex scope_exit serialization signals smart_ptr spirit statechart static_assert system thread timer tokenizer tr tuple type_traits typeof units unordered utility variant wave xpressive
